' Application led October 28, 1914. Serial No. 869,005.

' railway car windows; and it consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in allthe views.

Figure 1 is a front elevation, dpartly broken away, of a window provide 'with a preferable form of this rack.

Fig. 2 is an enlarged inner face view,

. partly in section, of this rack, the contignous part of the window sash and catch carried thereby being also shown. f Fig. 3 is a fragmentary perspective View of the form of rack shown in the preceding figures.

This rack comprises a strip of sheet metal formed with a series of slots and integral loops arranged in the rear of the slots and opposed thereto andjoined at vtheir ends lto the body of the strip at the ends of the slots,

said loops being open at their sides and hence, disconnected from the body ofthe strip at the sides of the slots.

1 designates the window sash. 2 is the catch which is 4operated by a suitable handle 3.

4 designates the rack which in this embodiment of my invention is formed on the inner stop of the Window frame.

The rack is, in this form of my invention, shown as provided on a strip of sheet metal which is bent in the form of a channel. As here shown, said strip is shaped to form two' channels 5, 6 facing in opposite directions, the walls of the channel 5 forming the body of the stop, and the channel 6 being a guide for the wlndow curtain.

The rack is provided in one of the'sides of the channel 5, that is, the side 7 opposed to the front face of the window sash 1, the side 7 being formed with a plurality of slots 8 and loops v9 in the rear of the bodyy or intact portion of the side 7. The loops 9 are connected at corresponding ends to the body. oit-intact portion of the side 7 at the ends of the slots. Usually all of the loops with the exception of the lower one, are connected at their opposite ends vat the ends of the slots. The loops 9 which are joined at both ends to the body of the strip are formed with inclined faces 10 and abrupt faces 1l, the inclined faces constituting ratcheting surfaces for the nose 12 of the catch 2 when the window is being raised, and the abrupt surfaces 11 forming shoulders for engaging the end of the catch 2 to hold the window from falling by its own weight to its closed position.

The loop 9, associated with thelowermost slot 8, is connected at its lower end only to the body or intact portion of the side 7 and is disconnected therefrom at its upper end so that the upper end of the lowerrnost slot forms an abrupt shoulder for engaging the nose 12-of the catch 2 in order to lock the window sash 1 in its closed position'.

This rack is formed by providing a strip of sheet metal, that is, the side 7 with the series of parallel slits and indenting or stretching inwardly the .portion of the metal between the slits.- v

What I claim is f l 1. The combination of a window frame, a sash movable in the frame, a catch associated with the Window, a rack associated with the frame and arranged to be engaged by the catch, the rack comprising a strip of sheet metal having a series of slots spaced apart and loops opposed toI the slots and connected at their ends to the body of the strip at opposite ends of the slots and separated' at the side edgesfrom the body of the strip, the end portions of the loops being arranged to be engaged by the catch and thus relieve the end walls of the slots, substantially as and for the purp0se`described.

2. A rack for windows comprising a strip of sheet metal formed with a series of slots spaced apart, and `loops opposedv to the slots and connected to the body of the'strip at the' opposite ends of the slots, the loops being open at their sides and hence disconnected from the body of the strip at the sides of the slots, 'and being provided at their opposite ends with incline and abrupt portions, substantially as and for the purpose specified.

`3. A Window stop comprising a sheet metal strip lbent in the form of a channel, one of the walls of the channel being formed with a series of slots and loops connecting the ends of the slots, the loops projecting into the channel, substantially as and for ythe purpose set forth. J y

4. The combinationof a Window frame, a sash movably mounted in the frame, a Window 'stop arranged to engage one of the faces ofthe sash at the margin thereof and comprising a strip of sheet metal in the form of a channel and arranged with the oute'r 'face of one of the walls of theV channel opposed to'the'm'argin 'of the' sash, said -wall being formed with a series of openings therein, and loops extending into the channel and connected'at their ends to the main part of the wall, and a catch mountedpon the sash and coacting with the openings and V the ends of the loops, to hold the Window in any adjusted position, substantially as and for the purpose described.

5. The combination of a'window frame, a sash movably 'mounted in the frame, a

window stop arranged to engage one of the faces of the sash at the margin thereof and comprising a strip of sheet metal in the form ofa ychannel arranged with the outer face of one of the Walls of the channel opposed to the margin of the sash, said Wall beingv formed "with a series of openings therein and integral loopsoffset from the openings and-.proj ecting into the channel and joining at their ends the main part of said Wall at the ends .of the openings, each.loop having inclined`
